Det er særlig egnet som middel for bruk etter nærværende oppfinnelse, da det er en sterk korrosjonsinhibitor for aluminium, slik at rester, ikke vasket ut, har heller en korrosjonshemmende enn korro-sjonsfremmende effekt på de sammenval- lig and can be easily washed out from the extended passages. It is particularly suitable as an agent for use according to the present invention, as it is a strong corrosion inhibitor for aluminium, so that residues, not washed out, have a corrosion-inhibiting rather than a corrosion-promoting effect on the aggregates.

Da blekket skal trykkes ved hjelp av silketrykkmetoden og derfor må holdes som en suspensjon i bæreren må det dis-pergerte metallsalt være meget finmalt. As the ink is to be printed using the screen printing method and must therefore be kept as a suspension in the carrier, the dispersed metal salt must be very finely ground.
Etter trykking har bæreren tendens til å After printing, the carrier tends to
tørre ut, og følgelig er det foretrukket å innarbeide et bindemiddel i blekket for å dry out, and consequently it is preferred to incorporate a binder in the ink in order to
